EiceDRIVER™ 1ED38x0Mc12M Enhanced Datasheet 3 Pin configuration and functionality FLT_N fault output and fault-off input
Open-drain output reports the failures related to operating of the inverter system to the microcontroller, fault output is active low. Fault-off input switch the gate driver output to off with fault-off function, input is low active. Connect to a microcontroller with 5 V or 3.3 V I/O with an external pull-up resistor to VCC1. A typical value for this resistor is 2.2 kΩ. The FLT_N signal is referenced to GND1.
IN non inverting gate driver input
IN input controls the output of the gate driver IC, the IGBT is turned on if IN is set to high. Connect to a PWM output of the microcontroller with 5 V or 3.3 V IO. An internal pull-down resistor ensures IGBT off-state if not connected.
VEE2
Negative power supply terminal of the output side. Connect to a voltage of 0 V to -25 V referenced to GND2 for proper operation. Place a decoupling capacitor close to the following pins: • VCC2 and VEE2 • GND2 and VEE2 If no negative supply voltage is used, all VEE2 pins have to be connected to GND2.
CLAMP Miller clamp output, Miller clamp pre-driver output, ADC input
The function and operating mode of this pin is depending on the register configuration. High-current clamp output to hold the gate voltage low during collector-emitter-voltage rise. Connect directly to the gate of the IGBT. Clamp pre-driver output for the use of an external clamp switch. Connect directly to the gate of a n-channel MOSFET. Sensing input for 8-bit ADC. Connect the external signal source between CLAMP and VEE2.
OFF driver output
High-current driver sink output to discharge the gate of the external IGBT and the two-level turn-off control output.The gate driver IC also sinks the Soft-off current at this pin. The pin is used as sense input for the gate high-level indicator
PINSTAT
.OFF_PIN and TLTOff comparator
PINSTAT
.TLTO_LVL. Connect to the gate of the IGBT via a chosen turn-off gate resistor.
ON driver output
High-current driver source output to charge the gate of the external IGBT and turn it on and sense input for the CLAMP function. It is also the sense input for the gate low-level indicator
PINSTAT
.ON_PIN. Connect to the gate of the IGBT via a chosen turn-on gate resistor.
DESAT enhanced desaturation detection input
Desaturation detection input to monitor the IGBT collector-emitter voltage (VCE) to detect desaturation caused by short circuit events. Connect to the collector of the driven IGBT via a series connection of a protection resistor and a high-voltage diode. The DESAT signal is referenced to GND2.
VCC2
Positive power supply terminal of the output side. Connect to sufficient supply voltage referenced to GND2 for proper operation. Place a decoupling capacitor close to the following pins: • VCC2 and VEE2 • VCC2 and GND2 Datasheet 9 v2.0 2020-03-26 Document Outline Table of contents 1 Block diagram 2 Related products 3 Pin configuration and functionality 3.1 Pin configuration 3.2 Pin functionality 3.3 Configurable parameters via I2C 4 Functional description 4.1 Start-up and fault clearing 4.2 Supply 4.3 Input side logic 4.4 I2C bus 4.5 Operating states 4.6 Measurement 4.7 Monitoring 4.8 Desaturation protection 4.8.1 DESAT behavior 4.9 Gate driver output 4.9.1 Turn-on behavior 4.9.2 Turn-off and fault turn-off behavior 4.9.2.1 Hard switching turn-off 4.9.2.2 Two-level turn-off 4.9.2.3 Soft turn-off 4.9.3 Active shut-down 4.9.4 Active Miller clamp 4.10 Short circuit clamping 5 Electrical parameters 5.1 Absolute maximum ratings 5.2 Thermal parameters 5.3 Operating parameters 5.4 Electrical characteristics 5.4.1 Voltage supply 5.4.2 Logic input and output 5.4.3 Gate driver 5.4.4 Active Miller clamp 5.4.5 Dynamic characteristics 5.4.6 Desaturation protection 5.4.7 Two-level turn-off 5.4.8 Soft-off current source 5.4.9 Over-temperature protection 5.4.10 ADC measurement 6 Insulation characteristics 6.1 Certified according to VDE 0884-11 and IEC 60747-17 reinforced insulation (planned) 6.2 Recognized under UL 1577 (planned) 7 Package information Revision history Disclaimer
